Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 4 is that interface board according to an embodiment of the invention can plug in the control method of port and can plug the schematic flow sheet that port is provided with password and disabled status for interface board.The main process of this flow process is, in the interface board production process, the maximum of fetch interface plate series number and this interface board can plug port number M, it is the plugged port number upper limit that interface board can hold, can plug port for then each password is set, and password is stored in the memory of interface board inside.Wherein, series number is the unique identification of interface board, and this series number is attached on the Handle Bar of interface board simultaneously, is stored in the memory and creation data storehouse of interface board, can pass through this series number is inquired about this interface board in the creation data storehouse details, as port password, date of manufacture or the like.
After this, these can plug port and be set to disabled status.Meanwhile, the series number of this interface board and the password that each can plug port are stored in the creation data storehouse, the creation data storehouse is to be used for a series of data that recording equipment and veneer production process thereof produce, as: equipment disposition, single board information or the like.The creation data storehouse is the database that device fabrication producer is used to store production process data.
Specifically, as shown in Figure 4, be provided with in the process of password can plugging port for interface board, at first, in step 100, fetch interface plate series number, and the maximum of this interface board can plug port number M; After this enter step 110, can plug port numbers X and be set to X=1; Enter step 120 then, password is set, and the maximum password input number of times Q that this can plug port is set for this can plug port x.Maximum password input number of times Q represents to allow to input mistakenly the number of times of password, surpasses this maximum password input number of times Q, and system will not allow the user to change the state that this can plug port.This will be described in more detail below.
Need to prove, meanwhile,, be stored in the creation data storehouse with this interface board series number and for each password that can plug the port setting respectively in step 170.
After this entering in the step 130, will be to plug the password that port x is provided with in step 120, and this maximum password input number of times Q that can plug port is stored in the memory of interface board inside; After this enter step 140, this state that can plug port x is set to disabled status, and any pluggable module of promptly inserting this port all can't operate as normal.After this, enter step 150, whether judgement can plug port numbers X can plug port number M more than or equal to the interface board maximum, if then the setting of password and disabled status has all been carried out in explanation to all the plugged ports on this interface board, this flow process finishes.Otherwise, illustrate still to have can plug port and do not carry out above-mentioned setting, then enter step 160, can plug port numbers X and be set to X=X+1, and return step 120, proceed to be provided with.
Need to prove, in above-mentioned flow process, can plug logic control element in the port, realize control, realize thus plugging " forbidding " setting of port to the incoming level of " transmitter turn-offs control " by interface board.Specifically, when " transmitter turn-off control " is input as high level, transmitter will turn-off, and promptly enter " forbidding " state.When " transmitter turn-off control " is input as low level, then transmitter will be opened, and promptly be in " enabling " state.In the interface board production process, can according in the above-mentioned flow process to the setting of " forbidding ", the level of " transmitter turn-offs control " is set to high level, and forbids this logic control level is reset, and the oralia that achieves a butt joint thus can plug " forbidding " control of port.When needs were enabled this and can be plugged port, after this can plug the proper password of port in input, logic control element " transmitter turn-offs control " level was set to low level, and permission resets this logic level, promptly was in the permission initiate mode.When realizing above-mentioned flow process, do not need to make any modification to typically plugging port circuit by this mode.
Can plug in the port device at interface board according to an embodiment of the invention, as shown in figure 11, can increase a K switch 1 in " input power supply VCC " that can plug port, the on off state of this K switch 1 is controlled by logic control element.In the production of interface board, according to " forbidding " setting of state that can plug port, the state of logic control element K switch 1 is set to open-circuit condition, and forbids this switch is reset, thereby realizes " forbidding " that can plug port controlled.When needs were enabled this and can be plugged port, behind the input proper password, the state of logic control element K switch 1 was set to close the road attitude, and allows it to reset, and promptly is in the permission initiate mode.
Except above-mentioned 2 kinds of implementation methods, the invention allows for several interface boards and can plug port device the disabled status setting.First kind as shown in figure 12, can plug port " input of transmission data " a plurality of K switch 1～Kn of increase, and control its on off state by logic control element.In the interface board production process, according to " forbidding " setting of state that can plug port, should organize on off state by logic control element and be set to the attitude of opening a way, and forbid this group switch is reset, thereby realize that " forbidding " controlled.When needs were enabled this and can be plugged port, when the input proper password, on off state was set to close the road attitude, and allows this group switch is reset, and was the permission initiate mode this moment.Second kind is as shown in figure 13, can plug port " receiving data exports " a plurality of K switch 1～Kn of increase, and by their on off state of logic control element control.In the interface board production process, according to " forbidding " setting of state that can plug port, should organize on off state by logic control element and be set to the attitude of opening a way, and forbid this group switch is reset, realize thus plugging " forbidding " control of port.When needs were enabled this and can be plugged port, behind the input proper password, the state of logic control element K switch 1～Kn was set to close the road attitude, and allows it to reset, and promptly is in the permission initiate mode.
In a word, by the described flow process of Fig. 4, all plugged ports that can dock one by one on the oralia carry out password setting, and these can plug port and are set to disabled status.
Fig. 5 illustrates in the control method that interface board according to an embodiment of the invention can plug port, and pluggable module is inserted flow process.Briefly, in this flow process, when having detected the pluggable module insertion, whether detection can plug port and enable, if enable, then directly finish, if still not enabled then ejects input password prompt frame, after waiting to import proper password, can plug port and change to the permission user mode, and be clearly zero the password enter counter.Need to prove that after the number of times of input error password reached the maximum password input number of times of setting continuously, system can point out and make mistakes, and, use or illegal the use to stop mistake with termination routine after the zero clearing of password enter counter.
Specifically, this flow process as shown in Figure 5, in the use of communication equipment, when pluggable module was inserted interface board and can be plugged port, it was on the throne at first to detect the pluggable module that can plug port x in step 200; After this enter step 210, judge that this can plug port x and whether enable, if enable, then do not carry out any operation and directly finish, otherwise, if this can plug port x not enabled still, then enter step 220, read maximum password input number of times Q, as mentioned above, be provided with in the flow process at password and disabled status, maximum password input number of times Q done being provided with and being stored in the memory of interface board inside.After this enter step 230, password enter counter Y is set to Y=1.Then enter step 240, input can plug the password of port x, and in this step, system can eject input password prompt frame.After this enter step 250, according to the password that is stored in the plugged port x in the interface board built-in storage, whether the password of judging the plugged port x of importing is correct, if it is correct, then enter step 260, enable and to plug port x, can plug port x and change to the permission user mode, and be clearly zero with the password enter counter, flow process finishes.Otherwise, if password is inaccurate, then entering step 270, system ejects prompting frame, the prompt cipher input error, and password enter counter Y is set to Y=Y+1.After this enter step 280, judge that according to the password enter counter whether password input number of times is more than or equal at above-mentioned password and disabled status the maximum password input number of times Q that is provided with in the flow process being set.If, illustrating that then the input number of times of bad password has reached the upper limit of setting, system will stop the normal use of this pluggable module, and flow process directly finishes.Otherwise, return step 240, input can plug the password of port x once more.
By the flow process of Fig. 5, can realize enabling and can plugging port by inputing correct plugged port password, the user error of forbidding continuous input error password simultaneously uses or illegally uses interface board can plug port.
Fig. 6 is that interface board according to an embodiment of the invention can plug in the control method of port, allows to enable or forbid the schematic flow sheet of setting to plugging port.According to the present invention, in interface board uses,, can enable or forbid some ports that plugs no matter can plug whether pluggable module is arranged on the port.At first need to input the password that this can plug port,, then select to enable or forbid this and can plug port,, then enable this and can plug port, termination routine if select to enable if password is correct; If select forbidding, whether on the throne, if not on the throne, then forbid this and can plug port if then detecting this pluggable module that can plug port, if on the throne, then system sends prompting frame, and whether the prompting user reselects forbids this and can plug port.If the user selects " being ", then forbid this and can plug port, termination routine.If select " denying ", then direct termination routine.Need to prove that if in above-mentioned setting up procedure, the number of times of input error password surpasses the maximum password input number of times that sets in advance, then system will point out, and with counter O reset, termination routine.
Specifically, as shown in Figure 6, in step 300, prepare to revise the state that can plug port x on the interface board; After this enter step 310, read maximum password input number of times Q, as mentioned above, be provided with in the flow process in password and disabled status this parameter is provided with.Then enter step 320, password enter counter Y is set to Y=1; Then enter step 330, input can plug the password of port x; After this enter step 340,, judge whether the password of input is correct,, otherwise enter step 350 if correctly then enter step 370 according to the password of the plugged port x that above has been provided with and has stored.
In step 350, system prompt password mistake, and password counter Y is set to Y=Y+1; After this enter step 360, judge that whether password input number of times Y is more than or equal to maximum password input number of times Q, if illustrate that then the number of times of continuous input error password has reached the upper limit that is provided with, therefore direct process ends.If not, then return step 330, re-enter and to plug the port x password.
In step 370, judge that needing forbidding still to enable can plug port x.If enable, then enter step 380, to enable and can plug port x, flow process finishes; If forbidding then enters step 390.
In step 390, whether judgement can plug the pluggable module of port x on the throne, if not on the throne, then enters step 400, forbids this and can plug port x; If on the throne, then enter step 410.
In step 410, it is on the throne that system prompt can plug the pluggable module of port x, and whether confirmation request is forbidden this and can be plugged port x.If confirm that not forbidding this can plug port, then flow process directly finishes; This can plug port x if confirm forbidding, then enters step 420, and forbidding can plug port x, and flow process finishes.
In flow process as shown in Figure 6, can allow to enable or forbid setting to plugging port by the correct password of input, prevent wrong the use or illegal the use simultaneously.
In according to another embodiment of the invention, the plugged port of interface board and password are not corresponding uniquely mutually, the one or more ports that plug of same cipher control.
